1 Claim.

My invention relates to improvements in distributing machines for use in road construction Work. i

The principal object of the invention is to provide a practical distributing-machine for attachment as a trailer for a dump truck to receive binding material such as soil, or gravel, from the truck and deposit the same on the road evenly to a predetermined depth, and which is simple in construction, economical in operation and in which the speed of operation as regards deposit of the binding material is governed by the speed of travel of the machine over the road.

To the accomplishment of the above, and subordinate objects presently appearing, a preferred embodiment of my invention is illustrated in the accompanying drawings, set forth in detail in the succeeding description, and defined in the claim appended hereto.

In said drawings:

Figure 1 is a View in side elevation of the preferred embodiment of my invention,

Figure 2 is a view in front elevation of the hitch,

Figure 3 is a view in top plan,

Figure 4: is a view in rear end elevation,

Figure 5 is a view in longitudinal section taken on the line 5-5 of Figure 3.

Referring to the drawings by numerals, the distributing machine of my invention, comprises, as its basic structure, a pair of side bars I of channel iron underslung intermediate the ends thereof from a wheel supported axle 2 by means of bearings 3 bolted, as at 4, to blocks 5 suitably secured on top of said bars. The ground wheels 6 are preferably equipped with rubber tires "1, pneumatic, or solid, as desired.

A pair of front and rear conveyor rollers 8, ii, are fitted between front and rear ends of said side bars I, respectively, to extend transversely thereof, said rollers being fast upon axial shafts l0 journalled at the ends thereof in bearings H, bolted, as at l2, to the tops of said side bars i. An endless conveyor, or apron, l3, preferably of rubber, is trained around said rollers 8, 9. The rear roller 9 is driven by means of a pair of rubber-tired driven Wheels M of substantially smaller diameter than the ground wheels 6 and which are fast upon opposite ends of the shaft IU of said roller 9 and frictionally engaged peripherally with the ground wheels 6 in the rear thereof so that said ground Wheels and driven wheels l4 form a friction drive for said conveyor adapted to drive the same in a direction such that the upper stretch thereof travels rearward- 1.v.

A platform It: extending between the rollers 8, 9, supports the upper stretch of the conveyor i3. Argch beams l6 of T-iron form arising from the side bars I and. extending across said platform support the latter, said beams being con-- nected to said bars I in any suitable manner.

At the front end of the machine, in front of the ground wheels ,5, and above the front end of the conveyor i3 is a feed hopper I! having an open bottom I8 spaced close to said top stretch of the conveyor, a forwardly and upwardly inclined front is, upwardly and outwardly inclined sides 28 and a rear Wall 2! perpendicular to said conveyor and provided with a lower opening 22 therein form a discharge gateway. A slidable gate 23 is provided alongside the rear Wall 2! of said hopper for vertical adjustment toopen the described discharge gate way formed by the opening 22, said gate having its ends slidably mounted in vertical guides 25 suitably secured to said rear Wall 2i. It is contemplated that the gate 23 be calibrated in any suitable manner, not shown, for adjustment to accurately Vary the size of the opening 22 so as to predetermine the discharge therethrough.

A pair of uprights 26 arising from the front ends of the bars I, respectively, and bolted, as at 21, to the front wall it of hopper i'l support the front of said hopper. An angle iron arch beam 28 arising from the side bars 5, and extending across the top edge of rear Wall 2i of the hopper i! and suitably secured thereto supports the rear side of said hopper.

A pair of upstanding side panels 29 extend rearwardly from the rear wall 2! of hopper ll along opposite sides of the conveyor 83, respectively, to the approximate vertical center of the rear roller 9, said panels being supported and slightly spaced above the upper stretch of the conveyor l3 by uprights 3i arising from the bars i. The panels 29 are provided with inwardly extending ledges 3| along the bottom edges thereof overlying the top stretch of the conveyor [3 and serving a purpose which will be apparent,

At the front end of the machine a hitch is provided for coupling the machine to the rear end of chassis 32 of a rearwardly dumping truck so that the truck body, represented at 33, may be emptied into the hopper IT. The hitch comprises a crank shaft 34 in front of the hopper l'l extending transversely of the machine and provided at one end with an operating crank 35 and adjacent its opposite end with a reel 36 fast thereon and disposed in the longitudinal center of the machine. Bearing brackets 31 suitably secured to the front wall I9 of the hopper I! support said shaft 34. A pair of keeper bars 38 extending inwardly and upwardly from the front ends of bars I respectively, and provided with terminal end thrust bearings 39 for the shaft 34, upon opposite sides of the reel 36, respectively, prevent end play of said shaft and reel. A ratchet and pawl detent, represented at 40, is provided for holding the shaft 34 and reel 36 against rotation in one direction, A chain 4| is secured at one end to said reel for winding thereon and provided at its other end with a ring 42 for attachment to a suitably mounted coupling pin 43 on the chassis 32 of the truck.

The operation of the described machine will be readily understood. The soil, or gravel, is dumped from the truck body 33 into the hopper I! to be carried from the latter 0n the conveyor l3 by way of the discharge opening 22, or gateway, and rearwardly between the panels 29 to be thrown rearwardly from the conveyor onto the road in a uniform layer, the conveyor being driven, in the manner already described, as the machine is pulled forwardly by the dump truck. The thickness of the layer of binding deposited may be varied by adjustment of the gate 23. By operation of the crank shaft 34 the chain 4| may be wound up, or unwound, to adjust the hopper I! to a suitable level below the dump body 33 of trucks of different heights, the adjustment being efiected, as will be understood, by tilting the machine on the axle 2.

The foregoing will, it is believed, suffice to impart a clear understanding of the construction, operation and advantages of my invention, without further explanation.

Manifestly, the invention as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the subjoined claim.

What I claim is In a machine of the class described, an axle, a pair of wheels supporting said axle, a frame underslung midway of its ends from said axle and including a pair of side bars, a pair of front and rear end rollers, respectively, journaled on said bars, to extend between the same on opposite sides of said wheels, respectively, an endless apron trained around said rollers with its upper stretch above the axle, a hopper mounted on said bars in front of said wheels and above said upper stretch in closely spaced relation to the latter and having a rear opening therein directly over said stretch whereby under travel of said stretch rearwardly material will be displaced from the hopper by said stretch and ejected rearwardly off the apron, a platform mounted on said bars and extending between said rollers in supporting relation to said upper stretch, a pair of side panels mounted on said bars, respectively, to extend along opposite side edges of said upper stretch, respectively, to confine the material on said stretch, and a friction drive between one of said wheels and one of said rollers for driving said upper stretch rearward-1y under forward travel of the machine.
